TIE-PLATE.

Specification of Letters Patent. Application filed November 22, 1909.

Patented May N, 119101. Serial No. 529,397.

Be it known that I, WILLIS McKEE, a resident of Elyria, in the county of Lorain and State of Ohio, have invented a new and useful Improvement in Tie-Plates; and I do hereby declare the following to be a full,

. clear, and exact description thereof.

My invention relates to'tie-plates and such as are used inconnection with railway rails for fastening such rails to the ties under the same.

The object of my invention is to provide a cheap, simple and eflicient form of a tieplate for railway rails, which can be manufactured by rolling in a rapid, easy and convenient manner and will provide for the proper supporting of the rail used'on such plates, as well as such a plate which will .hold spikes and rail in proper position, and

will provide means for the proper supporting of the headset the spikes employed therewith, particularly what are known as screwspikes, when used in connection therewith and at any position on the same along the edge of the-rail.

My invention consists, generally stated,

in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and particularly pointedont inthe claims To enable othersskilled in the art to which my invention appertains to construct and use my improved tie-plate, I will describe the saine more fully, referring to the accompanying drawing, in which- Figure 1 isfa top plan view of my improved tie-plat'. Fig. 2 is an end view of the same. Fig. 3 is a section of the plate on the line 3-3 Fig. 1 and showing the Same in position on a tie and supporting a rail.

Like symbols of reference herein indicate like parts in each of the figures of the drawing.

As illustrated in the drawing, 1 represents my improved tie-plate, which is preferably formed by rolling the same from .a bar or billet of metal, such as steel into lengths,

and then such lengths are severed by being" i such shoulders and on said surface. De-

pending ribs or flanges 6 are also formed longitudinally of thetie-plate 1 and on the ,bottom surface 7 of the body portion 2 and are preferably of triangu ar shape with sharpened edges, as at 6 for entering the tie in the usual manner when in position thereon, as hereinafter described. The tieplate 1 is also provided with a series of bosses 8 which project upwardly from the top surface 4. on the body portion 2 of said plate and at the outer ends of the same beyond the shoulders 3. These bosses 8 extend longitudinally along the entire upper surface 4 of the plate 1, with preferably the bosses on one end being staggered with those on the other end, and they have their inner faces 9 extending at an upward and outward incline from their inner edges, while the outer faces 10 of the same are preferably sloped downward from-the outer edges of the faces 9 to the outer edges of the plate 1 to lighten the same.

.In the rolling operation of forming my improved tie-plate 1', the metalis rolled from a billet or bar into lengths, with the upper roll (not shown) forming the shoulders 3 and bosses 8 for each end or side of the plate and upon the upper surface 4 of the same and adjacent toand beyond said shoulders, while the flanges 6 are formed on the lower surface 7 of the plate by the lower roll (notshown) After thebar hasbeen so formed to shape, it is out or sheared across the same and preferably between the bosses 8 on each end of such bar to form the plates 1. Spikeholes 11 can be formed in the bar after it is so made or in the plates 1 after being out from said barior during the operation of cutting, as desired, and these holes can be formed in any number along the ends of the plate 1 so made from such bar by punching, drilling or in any other suitable manner, and in the position for the insertion of the screw-spikes 12 within the same for the engagement of the spike-heads 12 with the rail base 13 on the rail 13, when such rail is placed in position in the seat 5 between the shoulders 3 on said plate, as shown in Fig. 3. These spikes 12 in passing through the holes 11 in the plate 1 are screwed into the tie 14: and the inner portions of their heads 12 bear against the top of the rail flange or base 13, while their outer portions vbear against and have a line contact with the inner inclined faces 9 on the bosses 8 on said plate, according to the positions of said holes within such plate, and thereby reinforce the back of the heads on such spikes.

The bosses 8 on each end of theplate -1 are placed as close as possible to each other so that the bar or plate can be punched for the holes 11 at any point for the spikes 12, and such holes can be varied in number on each end of the plate and their positions changed on such ends, as desired.

If desired, the upper surface 4 of the plate 1 can be provided with depressions 15 to form broad'bearing surfaces 16 on said surface for the rail 13; as shown by dotted lines in Fig. 3 and various other modifications andv changes in the design and construction of my improved tie-plate may be resorted to,

without departing from the spirit of the invention or sacrificing any of its advantages. It will thus be seen that in my improved tie-plate the arrangement for supporting the backs of the spike-heads will back up such heads more efiiciently than in the usual con" structions of this class by reason of such bosses being properly located with respect to the rail at all times, although the location of the spikes with respect to the bosses may vary, and the spike-holes in some cases being both opposite and between the bosses will enable such bosses to form a more satisfactory bearingfor the spike-heads than in ordinary cases bythe bar being so rolled that there is proper backing up for such heads at any and every place along the bar. It will also be seen that in my improved tie-plate'the arrangement of the spike, sup porting bosses will prevent any collection of water or brine on the plate and will also prevent any Water or'brine from running down the spike holes, which will thereby overcome any possible rottening of the tie under the same and so preserve the life of such tie.

The bar from which my improved tieplate is formed will enable such plates to be rolled in continuous lengths and then sheared or cut from such bar, while the formation of such plate will enable the easy and rapid rolling-of'such bar, and permit the tie-plates to be formed therefrom rapidly and conveniently, so that with the formation of the spike-holes withinthe same the tie-plates are ready for instant marketing and use with the rails and ties.

What I claim as my invention and desire to secure b Letters Patent-is v v 1. A rol ed tie-plate for rails havin a rail-abutting shoulder on the upper sur ace of the plate, and a series of rolled bosses along said surface and beyond said shoulder for hearing against the back of thespikheads which bosses being so arranged as to form" a line contact with the back 'of the spike-heads to reinforce the same in Whatever position the spike-holemay be located.

2. A rolled tie-plate for rails having a rail-abutting shoulder on the upper surface of the plate, and a series of rolled bosses along said surface and beyond said shoulder for bearing against the back of the spikeheads, said bosses being provided with upwardly and outwardly inclined bearing surfaces for said'heads, and such bosses so arranged as to forma line contact with the back of the spike-heads to reinforce the same in whatever position the spike-hole may be in the same for the reception of screw-spikes,

4. A tie-plate for rails having holes with a rail-abutting shoulder on each side of the upper surface of the plate, and a series of bosses along each side of said surface and beyond said shoulders for bearing against the back of the spike-heads, said bosses being provided with the upwardly and outwardly inclined bearing surfaces for said head, and the bosses on one .side being staggered with those onthe opposite side and so arranged as to form a line contact with the back of the spike-heads in any position of said holes to'reinfo'rce the same.

In testimony whereof, I, the said WILLIS MoKnE, have hereunto set my hand.
